This is a '07 Honda Rubicon 500 that developed a worn cam/follower anyway it's higher mileage at 6,500 and has had TCW-3 640:1 on E091 fuel from day 1...comments welcome.

Do you have a better resolution photo of the piston top?

It looks exceptionally clean, but hard to tell.

Very interesting, I'm interested in the TCW3 thing myself.

I haven't seen an cylinder head of your vehicle before, but looking at the valves, they do look a bit darker and seem to have some crusty residue on the edges .... at least compared to my cylinder head valves that I've seen from my vehicles. Mine always looked lighter in color and matte.

Without a non-TCW 640:1 engine run under identical circumstances for comparison, I don't know how you could draw any conclusions at all. Do you?

Can't even draw "didn't hurt" as a conclusion. Interesting nonetheless

again this had developed a worn cam so that may have had some effect on the valve timing. I'm impressed...this thing creeps through the forest here at 5-10 mph for hours on end or at least very low rpms.

I'm less than impressed, a worn cam after 6500 miles - less than desirable for me

Why would you purposefully add oil to the fuel on a 4 cycle engine that doesn't require it?

Do a google search for " TCW-III 640:1 "

It's been around for several years. Seems to have a lot of benefits.

It seals the rings on a worn engine. That has been proven in a court of law.
